Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Introduction

The Cisco Secure Firewall 6100 Series is an AI-ready, ultra-high-end firewall, engineered to deliver exceptional throughput per rack unit. Optimized for high-performing data center and telecommunications mobility infrastructure environments, the 6100 Series features a multi-socket, multi-core architecture that enables rapid threat inspection. It’s dedicated cryptographic modules facilitate high-throughput IPSec and TLS connection termination at scale, providing industry-leading cryptographic performance within its two rack unit (RU) form factor.

Highlights

Table 1.           Key highlights of Cisco Secure Firewall 6100 Series

Secure Firewall 6100 Series with Firewall Threat Defense Software

Unmatched performance:

  Gain up to 570 Gbps of throughput from a single 2 rack unit device when enabling the next-generation firewall capabilities, including intrusion prevention system (IPS).
  Support wide variety of network module, starting from 1G to high performance 400G QSFP DD network modules.

Superior visibility:

  Gain insight into encrypted traffic at line rate with the Encrypted Visibility Engine (EVE). Selectively decrypt TLS 1.3 and Quick UDP Internet Connections (QUIC) traffic as necessary.
  Accurately identify and control more than 8200 applications, enabling precise policy enforcement across cloud, SaaS, and custom workloads.

Carrier-grade firewalling:

  Enable clustering, Carrier-Grade Network Address Translation (CGNAT), and carrier license package to obtain high performance for service providers.
  Inspect GPRS Tunneling Protocol (GTP), Session Initiation Protocol (SIP), Diameter, and other telecom protocols at scale.

Advanced threat defense:

  With SnortML, a machine learning technology for threat detection, you can protect your network against zero-day vulnerabilities without requiring new signature updates.
  Perform on-premises dynamic analysis with Spero, ClamAV and cloud-based sandboxing to detect and stop evasive malware.

Robust high availability:

  6100 Series features N+1 clustering scalability, N+1 fan redundancy, and 1+1 power redundancy.
  With its fail-to-wire network module, 6100 Series firewall enables continuous connectivity even in case of any data plane failure.

Simplified management:

  Define a policy once and enforce it across Cisco and third-party firewalls with the Mesh Policy Engine.
  Streamline rule creation and reporting with Cisco AI Assistant, a built-in capability of unified management platform.
